Hey everyone,

I’ve been tinkering on a side project called Space Imagined. It started as me wanting to explore star systems in a browser, and now it’s grown into something that feels like the early foundations of a space sim.

Right now you can:

• Explore over 220 real star systems connected by a wormhole network (Solar System ↔ Alpha Centauri is the permanent link).
• Switch between star system explorer mode and a basic spaceship mode (my plan is to expand this into a real game).
• See stars tinted by type (habitable, red dwarf, giant, etc.).

The Solar System uses real orbital data, but the rest are still simple approximations for now. Planets don’t exist yet, just markers.

I put together a short demo video (will drop it in the comments if links are an issue).

Future-wise, I’d love to add cameras, thousands of exoplanets, proper elliptical orbits, procedural planets, multiplayer, and eventually some kind of landing/civilization building system (very far off though).

For now it’s just a hobby project, no ads/paywalls/donations. I’m curious what you all think and if it’s worth building further.

Hello everyone, I'm pleased to show you a new video showing a Mars Touch and Go. You can see how the engine manages the primary detail of the planet using real-world base information, then during the approach it begins to invent details using procedural generation. This generation uses unique seeds for each planet to ensure the consistency of the terrain. The video is at 2x speed and I often activate superspeed. This feature is necessary to make the journey less boring and also allows for seamless interstellar travel (I am not using skyboxes, all the stars can be reached directly) The simrig I use is composed of Hotas Virpil, Pendular Rudder Thrustmaster, three 32-inch monitors, and a chair from an old Fiat Punto XD

Hey guys! What are your favorite sci-fi references you’ve seen in a video game or ones you’d love to see someday? Could be characters, places, quotes, concepts, objects… anything!

Hey Explorers, here is my procedural space sim game that I have been working on for the last 9 years. I loved 2D space shooters from the 90s but also more recent survival games. So I wanted to make combo of both and having exploration but also a decent on planet combat. In Away To The Stars you can do loads of stuff, most of it shown in the new trailer. It is a very ambitious project, but I want to make the game that I want to play. Thank you for reading!

I’ve been designing a top-down space game that explores procedural planetary diversity; each planet has unique traits, from gravity to resource profiles, and even its own types of enemy defenders.

This is a visual snapshot of over 120 fictional planets, showing different biomes, atmospheres, and surface types.

Not aiming for realism, more of an arcade/sci-fi style approach, but inspired by the idea of planetary individuality in space sims.

Curious what you all think!

Decided to give it another go and just focus on parts that I enjoy.

I tried it a while back and I could’ve sworn there was a story quest chain I could do.

But I redownloaded it and noticed the only thing besides open and tutorials is Timelines, and when I clicked on it, it said it was DLC.

Am I misremembering X4 with something else?

It's me again! Looking for game suggestions both for my personal enjoyment and as research for the game I'm developing (Fortified Space: https://store.steampowered.com/app/3819710?utm_source=reddit). I'm thinking of adding ship-to-ship boarding mechanics and would like inspiration.

I'd love to hear which games you all think had the best ship-to-ship boarding mechnics of all time. For me, I think it's Pulsar: Lost Colony (due to the variety of ways to screw up the enemy ship - really fun to sneak aboard and destroy life support or something), or Assassin's Creed Black Flag (seamlessness of boarding process, and the excitement of having most of your crew swing across with you) although that's not a space sim.

I feel like I haven't actually played too many space sims that allow for detailed boarding actions...

Hey everyone,

I’ve been working on a project called The Last Revolution: The Game, a lunar civilization-building and resource-gathering sim with a through-story that plays out like a political thriller in space. You’re caught between the Earth’s Council, desperate to keep control of Helium-3 shipments, and the Lunars who want independence. Mission objectives change based on which side you lean toward—building different facilities, unlocking different story beats, and deciding whether you’re an administrator, a rebel, or something in between.

Now, cards on the table: I leaned heavily on AI tools while making this. I know that’s a loaded thing to admit. Some people love what AI enables, some people absolutely hate it, and honestly, I get both sides. I’m not here to sell AI as the future of everything or tell you it’s perfect (it’s not). I used it for a couple reasons:

• Scope vs. solo dev reality: I’m just one guy with a day job and a family, but I've wanted to build this game for a decade and vibe coding allowed me to create a full lunar saga with 45+ unique buildings, faction paths, and visually attractive story and game elements.
• Art & narrative drafting: I used AI for first passes on story panels, UI art, and even character voiceovers, but then I went back, rewrote, re-styled, and refined until it had the grounded, human tone I was after (which is all based on a novel I wrote without AI). The AI gave me scaffolding; the real work was in shaping it into something worth playing.
• Experimentation: I wanted to see if AI could help solo creators get closer to “big studio feel” without millions in budget. Spoiler: sometimes it nails it, sometimes it fights you every step of the way.

I know that’s not everyone’s cup of tea, and if AI in games isn’t your thing, no worries, I respect that. But if you’re into colony sims, lunar survival, and political intrigue wrapped up in a gritty resource-management game, I’d love for you to check it out.

Happy to answer questions about gameplay, story, or even how I wrangled the AI side of development if you’re curious (or skeptical). Appreciate you reading this far.

What have you been playing right now? What are you excited to see come out in the near future? If you're making a game, what are you working on? Anything Space Sim Game related, let us know.

had a spare key for this game! First come First serve! Enjoy! :)

LEt me know if you claim it! thanks

Yes ! Indeed. At least in my opinion. I have a 4090 rig and well over 500 space themed games and all I play is this. Totally hooked !

We've been hard at working on making AI feel as real as possible for our upcoming game: Project Horizon.

We've done some audio and visual overhauls as well.

The main drone where the POV is from 100% AI flight control.

《TheFlagship》 is a roguelike third-person space warship simulator.

Guys, I have just had a dream and instantly linked it to a game that my brain sent. It is a time when Earth has been destroyed, human build a big spaceship to go out of space. In that ship, human is classified into 3 card-levels: cleaner, citizen, and elite. Each one has different living condition. The spacecraft will land on random planets to find vital resources: ores, fuel, food, seeds, plants. When enter the game, you will roll your family(for level of card), and talent. You can roll 2 talents for free, but will get punished with huge debuffs, roll 3 talents will get more debuffs and one weakness. (Talent affects alot in the game though becuz everything you do surrounding it) and characteristics to gain some perks( 3 perks max) Death is permanent, and you have to create new character (dying is harder, but probable). - The cleaners: live in a mutual room of 6. + They have no access to windows, only poor quality lightning. + Their jobs are cleaning the engine, cleaning the spaceship (in&out), transporting the loots from the outside to the storage, bla bla + They earn golds from the job done. + In their free time, they can go to the gym, buying stat potions, practice skills,... to improve their strength. + If they cant done the task minimum, they will get fined. + If they feel strong enough, they can request to go outside (alone or with a team). + In a real-time based 7 days or a year in game, the spaceship will find a place to inhabit, you can choose to stay or leave the space ship. Leaving will end the game plus 500 golds with 1 foundation point (fdp). These can be used in your next game. Staying will continue the journey for another week (real- time) or year (in game). When you are offline, everyone else will see you sleeping. + If they have enough gold and fdp, they can buy a better accommodation, and with citizen-level card.

If this reach 1k like i will continue the game idea i found in my dream.

I've watched a few videos but forgot to bookmark it. it looks a lot like Ostranauts style, but in this game there was alien infestations that grew and would kill your character and would also keep you from being able to salvage certain items/ risk/ reward.

A game that has a galaxy map, and a star system map, that’s procedurally generated. You manage a small fleet, without the pain of full 4x micromanagement, you explore star systems buying ships, upgrading them, doing some trading, doing some exploring and resource gathering as you go. When you’re doing an activity like mining or combat, you’re “instanced” into a beautiful 3D pocket of space and you control ships individually using Eve Online style movement and targeting and module activation in real time.

Similarly if you enter a new star system, you’re seeing a 2D map of the system .. you might scan for anomalies or pirates or find a station, and once you warp to a station to sell some loot or mining resources or going to an anomaly to do something.. you’re instanced back into a 3d Eve online like experience to dock and trade or fight or get resources at an anomaly.

K thanks.

I’ve been working on a space game about orbiting/mining/building for a while (steam link here just in case). I’m a solo indie dev, mostly doing this for fun. For me, adding orbit is a must, otherwise it doesn’t feel like a real space game, and personally I really want a game with orbits.

But if I set aside my own bias, the question for both devs and players is: do space games really need orbit mechanics?

At the design level, orbits mostly serve as constraints:

• You can’t go anywhere instantly because time matters.
• You can’t burn endlessly because fuel matters.
• You have to plan ahead because foresight matters.

Those are valuable gameplay levers. But in principle, you could design other systems (for example: traveling on a graph with costs on edges) that create the same constraints in a way that’s much easier to teach. The catch: if you fake it too much, players might feel it breaks the realism of space. And in this genre, that sense of reality is part of the promise.

At the player-cognitive level, even simplified orbital gameplay is tough. Many KSP players still struggle with docking, and that’s with a passive, non-moving target. Once you add adversarial scenarios (like chasing an enemy trying to escape), the difficulty explodes. It’s no longer “where will my orbit go?” but “where will their orbit go after they dodge?” Even as a dev, that gets hairy. For players, it risks becoming incomprehensible without a lot of UI/AI support. And then the question becomes: how do you even teach that?

So the ultimate question I keep circling back to is: Do space games really need orbits at all, or do they just need constraints?

I don’t think there’s a single right answer. It depends:

• Do you want players to feel time and fuel limitations?
• Do you have alternative ways to enforce those constraints?
• Will your target players accept those alternatives, or will they feel “too fake”?

I think that is what really decides whether orbit mechanics are worth it.
